JAMES FORRESTER AND JOHN S. SLATTERY, OF SAN FRANCISCO, CALIFORNIA, AS- SIGNORS TO F. & S. FITTING MACHINE 00., INC, A CORPORATION OF CALIFORNIA.
FRUIT FITTING AND SLICING MACHINE.
Application filed May 31, 1923. Serial No. 642,681.
T all whom it may concern:
Be it known that we, JAMES FoRRns'rER and JOHN S. SLATTERY, citizens of the United States, and residents of the city and county of San Francisco, State of California, have invented new and useful Improvements in Fruit Pittin and Slicing Machines, of which the following is a specification.
Our invention has for its object a simple 0 and efiicient mechanism for cutting the pits from fruit andthereafter slicing the fruit, and is particularly adapted to clingstone peaches.
Other objects will appear fromthe drawings and specifications which follow.
These objects We attain by positioning the fruit in cups or containers which thereafter are caused to travel under a positioning and gauging means by which the fruit pit is eX- 'actly located with respect to the cutting knives which then cut the pit free from the fleshy portions of the fruit. Thereafter the fruit is moved into a further position where the fleshy portions are out in a central plane to the pit, the said cutting being carried through from both sides to the already freed pit. I
Thereafter the cup carrying the fruit, with the several cuts completed, releases its hold and the fruit in its several parts is dumped into a hopper or other'machine, the
saidact of releasing also causing the sev eral severed parts to separate from each other and from the pit. The pit now being readily separated from the cut fruit by any conventional means as shaking screens.
By referring tothe accompanying drawings and description our invention will be more readily understood.
Referring to the figures:
Fig. 1 is a side elevation of a machine of my invention, with some of the unessential frame work and details left out to better show the operating. principles and essential elements. a
Fig. 2 is aplan of Fig. 1. Fig. 3 is an end elevation. Fig. 4 is a diagram of the cam and lever movements showing the operation of the pitting spoons. v,
Fig.5 is a front elevation of one of the fruit holding cups.
Throu hout the figures similar numerals refer to identical parts. A main frame work on which the movable the frame 1.
and the positioning spindles 25, 26, 27, then parts are mounted is shown at 1 from which standards 2, 3,, 41, extend for supporting the operating parts At 5 is shown a main driving shaft carrying also the eccentric 6 and cam 7, the former adapted to reciprocate the connecting rod 8 and loose crank 9 which carries pawl 10 actuating ratchet wheel 11, andthereby causing the shaft 12 to advance at regular intervals, each movement corresponding with one-half of the cycle of movement of the eccentric 6, thereby carrying the wheels 13 and the chain 15 reaved thereover. At 16 is an idler sprocket mounted upon the (shaft 17, also carried on As the shaft 5 rotates in the direction of the arrow 18, the chain 15 will advance in the direction of the arrow 19.
Mounted upon the chain 15 are a plurality of fruit carriers, each provided with cup elements 20, 20, supported by adjustable arms 21 and springs 22, the arms being ful-. crumed on vertically adjustable member 23 carried in the sleeve 24 which latter is mounted upon the chain 15 more particu larly described below.
The movement of the eccentric 6 and pawl and ratchet wheel 10 and 11 is so timed that during half of the ratchet movement, each of the fruit cups 20, 20, is positioned vertically under one or the other of the spindles 25, 26, 27, while the spindles are still in their raised or full line position. At this time the operator places the fruit which it is desired to be pitted and sliced 99 into one of the cups and the guide spindle then forces the fruit down into the cup halves 20, 20, compressing the springs 21 until the fruit is gripped in the said cup. In placing the fruit in the said position the operator knowing the position of the stem of the fruit which. corresponds with the top of the pit of the fruit, the fruit is positioned with its stem and therefore the pit upward force the fruit against the said spring action until it is positioned exactly the right depth in the cup halves20, 2.0. In other words under the guidance of. the operator and the action of the stems 25, 26, 27 the fruit is positioned from 28 to 29 with the pit 30 in the uppermost position. i j I The inovement of the ratchet and pawl by the crank arm 9 and eccentric 6 causes the cups to travel at such times as the spindles are stationary in their up position and when the spindles start downwardthecup is'fiz zed in its position thereunder until the fruit is properly positioned therein and the movements of the pitting spoons and cutter knives has simultaneously taken place on fruit more advanced in position in the machine.
It will be noted that the position, of the fruit, and particularly the pit 30 in the fruit, is first gauged by the vertical moving spindles and is thereafter advanced to the position 31 where it is again brought to a standstill. The fruit is now positioned under the spoon shaped knife 32, see also Fig. 1-. A further revolution of the eccentric 6 now rotates the cam member 7 carrying the roller 33 through a cycle of movements which actuates the lever 34, connecting rod 35 and lever 36, pivoted at 13, having the arms'37,38. These arms actuate respectively the .spoon knife 39 which now travels through the path 40. Coincident therewith the arm .38 through the connecting rod {t1 actuates the second spoon knife pivoted on thecenter 12. The spoon :knife 32 describes the path at cutting through thefleshy portions of the fruit 31 close to the pit 4L5, seealso Fig. 5. i
It will now be seen thatthe operation of theknife .32 while the fruit is in position 31, followed .at the next cycleof movement by the operation of the'knifei39 when the same fruit is in the position 416 has resulted in cutting a path entirely around the pit within the said fruit and thereby freeing vance for the said pit.
the pitfromthe fleshy portions ofthe fruit. The pit is still held, however, incased-in'the fleshy portions until the fruit is later sliced as will now-be described.
The next cycle of movement transfers the fruit from the position 46 to the position 457 where it undergoes the slicing operation. This slicing operation is caused coincidentally with the movement of the spindles 25, 26, 27, and cutters 32, 39, but' upon fruit which has previously passed through the said steps of positioning and cutting. The movement of the shaft 12 actuates the rod 48,:bell crank 19,, spindle 50 of Fig. l which in turn causes. the reciprocating rods 51, 52, respectively, of Fig. 2, to move the knife arms .53, 5 1, which are pivoted in the conventional way to the frame member 'to cause the knives 56, 57, to approach each otherbetween the two halves of the cup 20, 20, thus slicing the fleshy portion :of the fruit entirely around and to the pit, the
knives having spaces 58, 59, providing clear- The next movement of the shaft 5 carriesthe fruit in which the pit has now been out free from the flesh and the fleshy portion sliced in halves into position and further successive movements carry-the fruit around the sprocket screen or the like, the two halves separating and the pit falling clear thereof. I
It is preferable to arrange a shaking screen through which'the pit will pass but will restrain the now finished halves of the fruit, which being "free from the pits may be passed .into. the conventional peeling apparatus.
The cups continue on around-the machine again,-and again, come into position on the upper half ready to receivefresh fruit.
The shape of .the pitting knives .32, 39, is preferably asshown in =Fig.2wher'e it will be seen that they are made hollow, preferably having sharpened; edges. They 2111 also made adjustable on the spindle 71 (see=1+=ig. 4) whereby the radii paths 40,4141 which they describe in-the fruit about the pit may be varied to suit the sizes of -the pits, as determinedby a previous grading 'of the fruit.
Also it will be seen that the cup member 20, 20, (Fig. 5) carried on the spindle 23 grips the'fruit as it-passes from the positioning spindle towards the left of Fig. 1, by theaction of the roller 72, which is depressed by the cam plate 73; this pulls the spindle 23 downward against the track 74:. This downward movement of the spindle '23 forces the bell crank levers 75, 7 6, outward by forcing them to ride upon the rollers 77, 78, respectively,-carried on the stem 24 and this :movementof the bell crank levers force thecups20, 20, towards each other gripping the fruit 29 in its.initialpositiomand holding it so gripped, during the subsequent operations, viz: during the gauging under the spindles 25, .26, 27, and cutting under the pitting knives 32, 39, and slicing by the knives 56, 57-, and until the fruit arrives in the position GO-of Fig. 1, at which time ,the roller 72 rides free from the cam plate 73 and the cups .20, 20, release their gripping action upon. the now finished fruit enabling itto fall freely as above described.
Referring particularly to Fig. 5 it will beseen that the two ,halves 20 2,0, are pivoted upon the arms 80, 81, and are further spring separated therefrom by the springs 82 and 83 and that these arms are pivoted at 8 1, .8 5, respectively, to the before mentioned bell cranks, 75, ;76. These cranks in turn ,being pivoted'to the spindle 23. The operator places the fruit in the cups 20, 20, and under the action of the spindle 27 the fruit being positioned with'the pit 415 in the uppermost position it is depressed within the cups compressing the springs 82, 83 and the further springs 90, 91, until it occupies its final position of perfect adjustment ready for the subsequent operations .above described.
